Could you put the appropriate parenthesis in here? I can make out what b) is supposed to be, but only because I see how to go from b) to c). (Multiply both sides of the equation by (1 + y)^2 and expand.) But I can't make any sense out of how to go from a) to b). There are too many ambiguities in a).

Assuming e^(i*pi) is correct, to get your answer simply multiply through by (1+y)^2, expand, and then you'll have something more familiar. (If you're feeling daring, there is no need to expand - you can set x=1+y, multiply through by x^2 and solve for x. Then y=x-1...)

how would i do that "(If you're feeling daring, there is no need to expand - you can set x=1+y, multiply through by x^2 and solve for x. Then y=x-1...)"
or if you can't show me could you direct me to a site that does.

You need brackets on your first term on the RHS. At the moment it reads whereas I suspect you mean

It's the same principle as Swlabr stated in post 4. However, this time, you need to multiply through by (1+y)^3 and then expand

when you multiply by u^2 it gives

Solve for u (I suggest the quadratic formula) and then back substitute to find y. (Remember that -1 is not in the domain)
